In an experiment, a flashlight and a buzzer are each placed in a vacuum chamber connected to a vacuum pump. They are switched on, and the air is slowly removed from the chamber. A sensor placed outside of the vacuum
chamber records the output of each device.

Which conclusion does the experiment support?
A. Sound waves travel farther than light waves.
B. Sound waves need a medium to travel
C. Light waves travel slower than sound waves.
D. Lightwaves need a vacuum to travel.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

3. dark matter

empty space could also be a simple vacuum

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
